Investigation of Topography of Waterjet Generated Surfaces

Abstract

We use three-dimensional surface topography analysis for evaluation of waterjet generated surfaces. In the study the waterjet surfaces are separated into smooth and striation zones, where striation influence is negligible in the smooth, zone. It is found that the smooth zone has a random, moderately isotropic texture. with the height distribution nearly Gaussian. In the striation zone the major frequencies of the surface profile power spectra are independent of cutting parameters, while the amplitudes of these frequencies monotonically increase with cutting speed of depth of cut. The effects of cutting speed, depth of cut, orifice diameter, and abrasive size on the surface topography are also studied. This provides useful information for controlling process parameters to obtain smooth finished surfaces.
